WIRE-SPlRALlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 717,552, dated January 6, 1903.

Application filed June 6, 1901. Renewed June 12, 1902. Serial 110- 111,828. (No model.)

To all whom it may concern:

Be it known that I, GEORGE M. DEPEW, a citizen of the United States of America, residing in Oanandaigua, in the county of Ontario, in the State of New York, have invented a certain new and useful Improvement in Wire- Spiraling Machines, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.

My invention relates to machinery for bond ing wire into a spiral vform, my object being to provide a simple and efiicient machine for this purpose.

The essential feature of my invention consists in the combination of a revolving perforated spindle having set or formed in its perforation bending-shoulders with means for feeding a wire through the perforated and rotating spindle.

Reference being now had to the drawings, in which my invention is illustrated, Figure 1 is a plan view showing my twisting mechanism in simple form. Fig. 2 is an enlarged plan showing the spindle in longitudinal central section. Fig. 3 is a vertical section taken on the line 3 3 of Fig. 2, and Fig. 4 is a view illustrating the action of the bending shoulders or pins upon the wire.

A indicates the frame of the machine; B B, the bearings for the perforated spindle.

O O are the bearings for the driving-shaft; D D, bearings for the feed-rolls.

E is the driving-shaft, to which motion is imparted in any convenient way, this shaft having attached to it a gear-wheel E and a bevel-gear E.

F and f indicate the shafts supporting the feed-rolls. To the lower shaft F is attached the bevel-wheel F, driven by the bevel-wheel E and the said shaft has also attached to itv a gear-wheel lying immediately below and corresponding in size with the gear-wheel f through which it drives the upper shaft j. I

F f indicate the feed-rolls, attached to the shaft and through which the wire is fed to the bending mechanism proper.

Gisthe revolving spindle, supported in the bearings B B and having attached to it a gear-wheel G, engaged and driven by the gear-wheel E. The outer end of the spindle proper is externally threaded, as indicated at passing through the spindle is necessarily bent in order to pass the shoulders formed by the pins I.

J is a guide-piece screwing into the threaded end H of the spindle extension H and lying close to the peripheries of the feed-rolls.

K, Fig. 4:, indicates the straight wire, and K the spirally-bent portion of the wire.

The operation of the device is easily followed. The shaft E being set in motion drives the bendingspindle GH and the feedrolls F f The wire K, fed through the feedrolls and the guide J, is bent as it passes between the bending-shoulders of the pins I, ro tating with the spindle. The resulting bend is a perfect spiral, which in the construction illustrated is equivalent to winding the wire around a central line.

Having now described my invention, what Iclaim as new, and desire to secure by Letters Patent, is v 1. In a wire-twisting machine, a revolving perforated spindle, in combination with bending-shoulders set transversely in the perforation of the spindle and on op'positesides thereof to'bend the wire as it passes through said perforation, and means for feeding the wire through the revolving spindle.

2. In a wire-twisting machine, a revolving perforated spindle, in combination with bending-shoulders set transversely in the perforation of the spindle and on opposite sides thereof to bend the wire as it passes through said perforation,andfeed-rollsforfeedingthe wire for feeding the wire through the revolving through the revolving spindle. spindle.

3. In a wire-twisting machine, a revolving perforated spindle,in combination with bend- GEORGE DEPEW 5 ing-shonlders I, I, I set in the perforation of WVitnesses:

the spindle as described to bend the Wire as VINCENT ROSEMON, it passes through said perforation, and means BEVERLEY ROBINSON.
